The original DHCP specification includes a route option but it supports only class-based routes. RFC3442 adds support for specifying the netmask width for each static route. A variable length encoding is used to minimize the size of this option. PR: bin/99534 Submitted by: Andrey V. Elsukov Reviewed by: brooks

Fix rev 1.12.

/tmp may not be writeable yet when dhclient is first run via /etc/rc.d/netif so using it may not work. Also, writing to a predictable file in /tmp as root is a really bad idea since a malicious user may be able to win a race and insert a symlink which will allow them to cause any file to be overwritten. To solve these problems, create the tempory file in /var/run which will exist this early and is writable only by root. Security: Local risk if users can cause dhclient to run on demand (such as by unplugging and replugging the network cable).
